Hints assignment 1.3

These are the hints for assignment 1.3. Not all these hints are necessary for successfully completing the assignment.

1. You can use the tokenization commands that you have created in assignment 1.1 in this exercise as well.

2. You should try to construct a file containing trigrams. You can use the same trick as in assignment 1.2. First create a file containing bigrams and then paste a list next to it. The following list of the initial trigrams may help you to decide what to do:

                   The
           The     Fulton
   ---------------------- 
   The     Fulton  County
   Fulton  County  Grand
   County  Grand   Jury
   Grand   Jury    said
   Jury    said    Friday
   said    Friday  an
   Friday  an      investigation
   

3. Your trigram list will end with a line containing two words followed with a line containing one word. Are you going to regard these as trigrams?
